Abstract: PURPOSE: A system for sharing base stations of a mobile communication system is provided to configure a radio frequency(RF) terminal for simultaneously processing signals from each provider in a single base station, so as to expand service areas to reduce a call drop rate. CONSTITUTION: In a transmission path of a base station, a radio frequency(RF) signal transmitted from an existing PCS transmitter is amplified into a specific gain according to each provider by a second low noise amplifier(321), and synthesized via a second isolator(320) by a channel combiner. The synthesized signal is combined with a reception path by a junction(314) and copied to a free space from an antenna(311). The second isolator is equipped between the channel combiner and the low-noise amplifier, so that signals from other channels of one provider can be prevented from being inputted and individual signals from one channel can be prevented from being returned reflectively. In the reception path, an RF signal received through the antenna passes through the junction to penetrate receiving bands of each provider by a receiving filter(315). The penetrated signal is amplified into a specific gain and separated by a power divider(317) to be inputted to an existing PCS receiver via a first isolator(318).
